This document demonstrates the development of a simple Go package and
|
|
||||||
introduces the <a href="/cmd/go/">go tool</a>, the standard way to fetch,
|
|
||||||
build, and install Go packages and commands.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The <code>go</code> tool requires you to organize your code in a specific
|
|
||||||
way. Please read this document carefully.
|
|
||||||
It explains the simplest way to get up and running with your Go installation.
|
|
||||||
</p>
|
|
||||||
|
|
||||||

<h3 id="Overview">Overview</h3>
|
|
||||||
|
|
||||||
<ul>
|
|
||||||
<li>Go programmers typically keep all their Go code in a single <i>workspace</i>.</li>
|
|
||||||
<li>A workspace contains many version control <i>repositories</i>
|
|
||||||
(managed by Git, for example).</li>
|
|
||||||
<li>Each repository contains one or more <i>packages</i>.</li>
|
|
||||||
<li>Each package consists of one or more Go source files in a single directory.</li>
|
|
||||||
<li>The path to a package's directory determines its <i>import path</i>.</li>
|
|
||||||
</ul>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Note that this differs from other programming environments in which every
|
|
||||||
project has a separate workspace and workspaces are closely tied to version
|
|
||||||
control repositories.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<h3 id="Workspaces">Workspaces</h3>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
A workspace is a directory hierarchy with two directories at its root:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<ul>
|
|
||||||
<li><code>src</code> contains Go source files, and
|
|
||||||
<li><code>bin</code> contains executable commands.
|
|
||||||
</ul>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The <code>go</code> tool builds and installs binaries to the <code>bin</code> directory.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The <code>src</code> subdirectory typically contains multiple version control
|
|
||||||
repositories (such as for Git or Mercurial) that track the development of one
|
|
||||||
or more source packages.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
To give you an idea of how a workspace looks in practice, here's an example:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
bin/
|
|
||||||
hello # command executable
|
|
||||||
outyet # command executable
|
|
||||||
src/
|
|
||||||
<a href="https://github.com/golang/example/">github.com/golang/example/</a>
|
|
||||||
.git/ # Git repository metadata
|
|
||||||
hello/
|
|
||||||
hello.go # command source
|
|
||||||
outyet/
|
|
||||||
main.go # command source
|
|
||||||
main_test.go # test source
|
|
||||||
stringutil/
|
|
||||||
reverse.go # package source
|
|
||||||
reverse_test.go # test source
|
|
||||||
<a href="https://golang.org/x/image/">golang.org/x/image/</a>
|
|
||||||
.git/ # Git repository metadata
|
|
||||||
bmp/
|
|
||||||
reader.go # package source
|
|
||||||
writer.go # package source
|
|
||||||
... (many more repositories and packages omitted) ...
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The tree above shows a workspace containing two repositories
|
|
||||||
(<code>example</code> and <code>image</code>).
|
|
||||||
The <code>example</code> repository contains two commands (<code>hello</code>
|
|
||||||
and <code>outyet</code>) and one library (<code>stringutil</code>).
|
|
||||||
The <code>image</code> repository contains the <code>bmp</code> package
|
|
||||||
and <a href="https://godoc.org/golang.org/x/image">several others</a>.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
A typical workspace contains many source repositories containing many
|
|
||||||
packages and commands. Most Go programmers keep <i>all</i> their Go source code
|
|
||||||
and dependencies in a single workspace.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Note that symbolic links should <b>not</b> be used to link files or directories into your workspace.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Commands and libraries are built from different kinds of source packages.
|
|
||||||
We will discuss the distinction <a href="#PackageNames">later</a>.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
|
|
||||||
<h3 id="GOPATH">The <code>GOPATH</code> environment variable</h3>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The <code>GOPATH</code> environment variable specifies the location of your
|
|
||||||
workspace. It defaults to a directory named <code>go</code> inside your home directory,
|
|
||||||
so <code>$HOME/go</code> on Unix,
|
|
||||||
<code>$home/go</code> on Plan 9,
|
|
||||||
and <code>%USERPROFILE%\go</code> (usually <code>C:\Users\YourName\go</code>) on Windows.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
If you would like to work in a different location, you will need to
|
|
||||||
<a href="https://golang.org/wiki/SettingGOPATH">set <code>GOPATH</code></a>
|
|
||||||
to the path to that directory.
|
|
||||||
(Another common setup is to set <code>GOPATH=$HOME</code>.)
|
|
||||||
Note that <code>GOPATH</code> must <b>not</b> be the
|
|
||||||
same path as your Go installation.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The command <code>go</code> <code>env</code> <code>GOPATH</code>
|
|
||||||
prints the effective current <code>GOPATH</code>;
|
|
||||||
it prints the default location if the environment variable is unset.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
For convenience, add the workspace's <code>bin</code> subdirectory
|
|
||||||
to your <code>PATH</code>:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>export PATH=$PATH:$(go env GOPATH)/bin</b>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The scripts in the rest of this document use <code>$GOPATH</code>
|
|
||||||
instead of <code>$(go env GOPATH)</code> for brevity.
|
|
||||||
To make the scripts run as written
|
|
||||||
if you have not set GOPATH,
|
|
||||||
you can substitute $HOME/go in those commands
|
|
||||||
or else run:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>export GOPATH=$(go env GOPATH)</b>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
To learn more about the <code>GOPATH</code> environment variable, see
|
|
||||||
<a href="/cmd/go/#hdr-GOPATH_environment_variable"><code>'go help gopath'</code></a>.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
To use a custom workspace location,
|
|
||||||

|
||||||

|
|
||||||
|
|
||||||
<h3 id="ImportPaths">Import paths</h3>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
An <i>import path</i> is a string that uniquely identifies a package.
|
|
||||||
A package's import path corresponds to its location inside a workspace
|
|
||||||
or in a remote repository (explained below).
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The packages from the standard library are given short import paths such as
|
|
||||||
<code>"fmt"</code> and <code>"net/http"</code>.
|
|
||||||
For your own packages, you must choose a base path that is unlikely to
|
|
||||||
collide with future additions to the standard library or other external
|
|
||||||
libraries.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
If you keep your code in a source repository somewhere, then you should use the
|
|
||||||
root of that source repository as your base path.
|
|
||||||
For instance, if you have a <a href="https://github.com/">GitHub</a> account at
|
|
||||||
<code>github.com/user</code>, that should be your base path.

|
|
||||||
<p>
|
|
||||||
Note that you don't need to publish your code to a remote repository before you
|
|
||||||
can build it. It's just a good habit to organize your code as if you will
|
|
||||||
publish it someday. In practice you can choose any arbitrary path name,
|
|
||||||
as long as it is unique to the standard library and greater Go ecosystem.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
We'll use <code>github.com/user</code> as our base path. Create a directory
|
|
||||||
inside your workspace in which to keep source code:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>mkdir -p $GOPATH/src/github.com/user</b>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
|
|
||||||
<h3 id="Command">Your first program</h3>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
To compile and run a simple program, first choose a package path (we'll use
|
|
||||||
<code>github.com/user/hello</code>) and create a corresponding package directory
|
|
||||||
inside your workspace:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>mkdir $GOPATH/src/github.com/user/hello</b>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Next, create a file named <code>hello.go</code> inside that directory,
|
|
||||||
containing the following Go code.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
package main
|
|
||||||
|
|
||||||
import "fmt"
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
fmt.Println("Hello, world.")
|
|
||||||
}
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Now you can build and install that program with the <code>go</code> tool:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>go install github.com/user/hello</b>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Note that you can run this command from anywhere on your system. The
|
|
||||||
<code>go</code> tool finds the source code by looking for the
|
|
||||||
<code>github.com/user/hello</code> package inside the workspace specified by
|
|
||||||
<code>GOPATH</code>.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
You can also omit the package path if you run <code>go install</code> from the
|
|
||||||
package directory:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>cd $GOPATH/src/github.com/user/hello</b>
|
|
||||||
$ <b>go install</b>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
This command builds the <code>hello</code> command, producing an executable
|
|
||||||
binary. It then installs that binary to the workspace's <code>bin</code>
|
|
||||||
directory as <code>hello</code> (or, under Windows, <code>hello.exe</code>).
|
|
||||||
In our example, that will be <code>$GOPATH/bin/hello</code>, which is
|
|
||||||
<code>$HOME/go/bin/hello</code>.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The <code>go</code> tool will only print output when an error occurs, so if
|
|
||||||
these commands produce no output they have executed successfully.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
You can now run the program by typing its full path at the command line:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>$GOPATH/bin/hello</b>
|
|
||||||
Hello, world.
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Or, as you have added <code>$GOPATH/bin</code> to your <code>PATH</code>,
|
|
||||||
just type the binary name:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>hello</b>
|
|
||||||
Hello, world.
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
If you're using a source control system, now would be a good time to initialize
|
|
||||||
a repository, add the files, and commit your first change. Again, this step is
|
|
||||||
optional: you do not need to use source control to write Go code.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>cd $GOPATH/src/github.com/user/hello</b>
|
|
||||||
$ <b>git init</b>
|
|
||||||
Initialized empty Git repository in /home/user/go/src/github.com/user/hello/.git/
|
|
||||||
$ <b>git add hello.go</b>
|
|
||||||
$ <b>git commit -m "initial commit"</b>
|
|
||||||
[master (root-commit) 0b4507d] initial commit
|
|
||||||
1 file changed, 7 insertion(+)
|
|
||||||
create mode 100644 hello.go
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Pushing the code to a remote repository is left as an exercise for the reader.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
|
|
||||||
<h3 id="Library">Your first library</h3>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Let's write a library and use it from the <code>hello</code> program.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Again, the first step is to choose a package path (we'll use
|
|
||||||
<code>github.com/user/stringutil</code>) and create the package directory:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>mkdir $GOPATH/src/github.com/user/stringutil</b>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Next, create a file named <code>reverse.go</code> in that directory with the
|
|
||||||
following contents.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
// Package stringutil contains utility functions for working with strings.
|
|
||||||
package stringutil
|
|
||||||
|
|
||||||
// Reverse returns its argument string reversed rune-wise left to right.
|
|
||||||
func Reverse(s string) string {
|
|
||||||
r := []rune(s)
|
|
||||||
for i, j := 0, len(r)-1; i < len(r)/2; i, j = i+1, j-1 {
|
|
||||||
r[i], r[j] = r[j], r[i]
|
|
||||||
}
|
|
||||||
return string(r)
|
|
||||||
}
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Now, test that the package compiles with <code>go build</code>:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>go build github.com/user/stringutil</b>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Or, if you are working in the package's source directory, just:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>go build</b>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
This won't produce an output file.
|
|
||||||
Instead it saves the compiled package in the local build cache.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
After confirming that the <code>stringutil</code> package builds,
|
|
||||||
modify your original <code>hello.go</code> (which is in
|
|
||||||
<code>$GOPATH/src/github.com/user/hello</code>) to use it:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
package main
|
|
||||||
|
|
||||||
import (
|
|
||||||
"fmt"
|
|
||||||
|
|
||||||
<b>"github.com/user/stringutil"</b>
|
|
||||||
)
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
fmt.Println(stringutil.Reverse("!oG ,olleH"))
|
|
||||||
}
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Install the <code>hello</code> program:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>go install github.com/user/hello</b>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Running the new version of the program, you should see a new, reversed message:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>hello</b>
|
|
||||||
Hello, Go!
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
After the steps above, your workspace should look like this:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
bin/
|
|
||||||
hello # command executable
|
|
||||||
src/
|
|
||||||
github.com/user/
|
|
||||||
hello/
|
|
||||||
hello.go # command source
|
|
||||||
stringutil/
|
|
||||||
reverse.go # package source
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<h3 id="PackageNames">Package names</h3>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The first statement in a Go source file must be
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
package <i>name</i>
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
where <code><i>name</i></code> is the package's default name for imports.
|
|
||||||
(All files in a package must use the same <code><i>name</i></code>.)
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Go's convention is that the package name is the last element of the
|
|
||||||
import path: the package imported as "<code>crypto/rot13</code>"
|
|
||||||
should be named <code>rot13</code>.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Executable commands must always use <code>package main</code>.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
There is no requirement that package names be unique
|
|
||||||
across all packages linked into a single binary,
|
|
||||||
only that the import paths (their full file names) be unique.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
See <a href="/doc/effective_go.html#names">Effective Go</a> to learn more about
|
|
||||||
Go's naming conventions.

</p>
|
|
||||||
|
|
||||||
|
|
||||||
<h2 id="Testing">Testing</h2>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Go has a lightweight test framework composed of the <code>go test</code>
|
|
||||||
command and the <code>testing</code> package.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
You write a test by creating a file with a name ending in <code>_test.go</code>
|
|
||||||
that contains functions named <code>TestXXX</code> with signature
|
|
||||||
<code>func (t *testing.T)</code>.
|
|
||||||
The test framework runs each such function;
|
|
||||||
if the function calls a failure function such as <code>t.Error</code> or
|
|
||||||
<code>t.Fail</code>, the test is considered to have failed.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Add a test to the <code>stringutil</code> package by creating the file
|
|
||||||
<code>$GOPATH/src/github.com/user/stringutil/reverse_test.go</code> containing
|
|
||||||
the following Go code.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
package stringutil
|
|
||||||
|
|
||||||
import "testing"
|
|
||||||
|
|
||||||
func TestReverse(t *testing.T) {
|
|
||||||
cases := []struct {
|
|
||||||
in, want string
|
|
||||||
}{
|
|
||||||
{"Hello, world", "dlrow ,olleH"},
|
|
||||||
{"Hello, 世界", "界世 ,olleH"},
|
|
||||||
{"", ""},
|
|
||||||
}
|
|
||||||
for _, c := range cases {
|
|
||||||
got := Reverse(c.in)
|
|
||||||
if got != c.want {
|
|
||||||
t.Errorf("Reverse(%q) == %q, want %q", c.in, got, c.want)
|
|
||||||
}
|
|
||||||
}
|
|
||||||
}
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Then run the test with <code>go test</code>:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>go test github.com/user/stringutil</b>
|
|
||||||
ok github.com/user/stringutil 0.165s
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
As always, if you are running the <code>go</code> tool from the package
|
|
||||||
directory, you can omit the package path:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>go test</b>
|
|
||||||
ok github.com/user/stringutil 0.165s
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
Run <code><a href="/cmd/go/#hdr-Test_packages">go help test</a></code> and see the
|
|
||||||
<a href="/pkg/testing/">testing package documentation</a> for more detail.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
|
|
||||||
<h2 id="remote">Remote packages</h2>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
An import path can describe how to obtain the package source code using a
|
|
||||||
revision control system such as Git or Mercurial. The <code>go</code> tool uses
|
|
||||||
this property to automatically fetch packages from remote repositories.
|
|
||||||
For instance, the examples described in this document are also kept in a
|
|
||||||
Git repository hosted at GitHub
|
|
||||||
<code><a href="https://github.com/golang/example">github.com/golang/example</a></code>.
|
|
||||||
If you include the repository URL in the package's import path,
|
|
||||||
<code>go get</code> will fetch, build, and install it automatically:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
$ <b>go get github.com/golang/example/hello</b>
|
|
||||||
$ <b>$GOPATH/bin/hello</b>
|
|
||||||
Hello, Go examples!
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
If the specified package is not present in a workspace, <code>go get</code>
|
|
||||||
will place it inside the first workspace specified by <code>GOPATH</code>.
|
|
||||||
(If the package does already exist, <code>go get</code> skips the remote
|
|
||||||
fetch and behaves the same as <code>go install</code>.)
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
After issuing the above <code>go get</code> command, the workspace directory
|
|
||||||
tree should now look like this:
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
bin/
|
|
||||||
hello # command executable
|
|
||||||
src/
|
|
||||||
github.com/golang/example/
|
|
||||||
.git/ # Git repository metadata
|
|
||||||
hello/
|
|
||||||
hello.go # command source
|
|
||||||
stringutil/
|
|
||||||
reverse.go # package source
|
|
||||||
reverse_test.go # test source
|
|
||||||
github.com/user/
|

||||||
hello/
|
|
||||||
hello.go # command source
|
|
||||||
stringutil/
|
|
||||||
reverse.go # package source
|
|
||||||
reverse_test.go # test source
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>
|
|
||||||
The <code>hello</code> command hosted at GitHub depends on the
|
|
||||||
<code>stringutil</code> package within the same repository. The imports in
|
|
||||||
<code>hello.go</code> file use the same import path convention, so the
|
|
||||||
<code>go get</code> command is able to locate and install the dependent
|
|
||||||
package, too.
|
|
||||||
</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
import "github.com/golang/example/stringutil"
|
|
||||||
</pre>
|

The Go programming language is an open source project to make programmers more

productive.

Go is expressive, concise, clean, and efficient. Its concurrency
|
|
||||||
mechanisms make it easy to write programs that get the most out of multicore
|
|
||||||
and networked machines, while its novel type system enables flexible and
|
|
||||||
modular program construction. Go compiles quickly to machine code yet has the
|
|
||||||
convenience of garbage collection and the power of run-time reflection. It's a
|
|
||||||
fast, statically typed, compiled language that feels like a dynamically typed,
|
|
||||||
interpreted language.

One of Go's key design goals is code adaptability; that it should be easy to take a simple design and build upon it in a clean and natural way. In this talk Andrew Gerrand describes a simple "chat roulette" server that matches pairs of incoming TCP connections, and then use Go's concurrency mechanisms, interfaces, and standard library to extend it with a web interface and other features. While the function of the program changes dramatically, Go's flexibility preserves the original design as it grows.

Concurrency is the key to designing high performance network services. Go's concurrency primitives (goroutines and channels) provide a simple and efficient means of expressing concurrent execution. In this talk we see how tricky concurrency problems can be solved gracefully with simple Go code.

<!-- golang.org/issue/33848 -->

When the main module contains a top-level <code>vendor</code> directory and
|
||||||
|
its <code>go.mod</code> file specifies <code>go</code> <code>1.14</code> or
|
||||||
|
higher, the <code>go</code> command now defaults to <code>-mod=vendor</code>
|
||||||
|
for operations that accept that flag. A new value for that flag,
|
||||||
|
<code>-mod=mod</code>, causes the <code>go</code> command to instead load
|
||||||
|
modules from the module cache (as when no <code>vendor</code> directory is
|
||||||
|
present).
|
||||||
|
</p>
|
||||||
|
|
||||||
|
<p>
|
||||||
|
When <code>-mod=vendor</code> is set (explicitly or by default), the
|
||||||
|
<code>go</code> command now verifies that the main module's
|
||||||
|
<code>vendor/modules.txt</code> file is consistent with its
|
||||||
|
<code>go.mod</code> file.
|
||||||
|
</p>
|

<p>
|
||||||
|
<code>go</code> <code>list</code> <code>-m</code> no longer silently omits
|
||||||
|
transitive dependencies that do not provide packages in
|
||||||
|
the <code>vendor</code> directory. It now fails explicitly if
|
||||||
|
<code>-mod=vendor</code> is set.

The <code>go</code> <code>get</code> command no longer accepts
|
||||||
|
the <code>-mod</code> flag. Previously, the flag's setting either
|
||||||
|
<a href="https://golang.org/issue/30345">was ignored</a> or
|
||||||
|
<a href="https://golang.org/issue/32502">caused the build to fail</a>.

<code>-modcacherw</code> is a new flag that instructs the <code>go</code>
|
||||||
|
command to leave newly-created directories in the module cache at their
|
||||||
|
default permissions rather than making them read-only.
|
||||||
|
The use of this flag makes it more likely that tests or other tools will
|
||||||
|
accidentally add files not included in the module's verified checksum.
|
||||||
|
However, it allows the use of <code>rm</code> <code>-rf</code>
|
||||||
|
(instead of <code>go</code> <code>clean</code> <code>-modcache</code>)
|
||||||
|
to remove the module cache.

<code>-modfile=file</code> is a new flag that instructs the <code>go</code>
|
||||||
|
command to read (and possibly write) an alternate go.mod file instead of the
|
||||||
|
one in the module root directory. A file named "go.mod" must still be present
|
||||||
|
in order to determine the module root directory, but it is not
|
||||||
|
accessed. When <code>-modfile</code> is specified, an alternate go.sum file
|
||||||
|
is also used: its path is derived from the <code>-modfile</code> flag by
|
||||||
|
trimming the ".mod" extension and appending ".sum".

Native Client
|
|
||||||
=============
|
|
||||||
|
|
||||||
This document outlines the basics of building and developing the Go runtime and
|
|
||||||
programs in the Native Client (NaCl) environment.
|
|
||||||
|
|
||||||
Go 1.3 supports three architectures
|
|
||||||
|
|
||||||
* nacl/386 which is standard 386.
|
|
||||||
* nacl/amd64p32 which is a 64 bit architecture, where the address space is
|
|
||||||
limited to a 4gb window.
|
|
||||||
* nacl/arm which is 32-bit ARMv7A architecture with 1GB address space.
|
|
||||||
|
|
||||||
For background it is recommended that you read https://golang.org/s/go13nacl.
|
|
||||||
|
|
||||||
Prerequisites
|
|
||||||
-------------
|
|
||||||
|
|
||||||
Native Client programs are executed inside a sandbox, the NaCl runtime. This
|
|
||||||
runtime must be installed before you can use NaCl programs.
|
|
||||||
|
|
||||||
The NaCl distribution comes with an installer which ensures you have access to
|
|
||||||
the latest version of the runtime. The version tracks the Chrome numbering
|
|
||||||
scheme.
|
|
||||||
|
|
||||||
# Download NaCl
|
|
||||||
|
|
||||||
Download nacl_sdk.zip file from
|
|
||||||
https://developer.chrome.com/native-client/sdk/download
|
|
||||||
and unpack it. I chose /opt/nacl_sdk.
|
|
||||||
|
|
||||||
# Update
|
|
||||||
|
|
||||||
The zip file contains a small skeleton that can be used to download the correct
|
|
||||||
sdk. These are released every 6-8 weeks, in line with Chrome releases.
|
|
||||||
|
|
||||||
% cd /opt/nacl_sdk
|
|
||||||
% ./naclsdk update
|
|
||||||
|
|
||||||
At this time pepper_49 is the stable version. The NaCl port needs at least pepper_39
|
|
||||||
to work. If naclsdk downloads a later version, please adjust accordingly.
|
|
||||||
|
|
||||||
The cmd/go helper scripts expect that the loaders sel_ldr_{x86_{32,64},arm} and
|
|
||||||
nacl_helper_bootstrap_arm are in your path. I find it easiest to make a symlink
|
|
||||||
from the NaCl distribution to my $GOPATH/bin directory.
|
|
||||||
|
|
||||||
% ln -nfs /opt/nacl_sdk/pepper_39/tools/sel_ldr_x86_32 $GOPATH/bin/sel_ldr_x86_32
|
|
||||||
% ln -nfs /opt/nacl_sdk/pepper_39/tools/sel_ldr_x86_64 $GOPATH/bin/sel_ldr_x86_64
|
|
||||||
% ln -nfs /opt/nacl_sdk/pepper_39/tools/sel_ldr_arm $GOPATH/bin/sel_ldr_arm
|
|
||||||
|
|
||||||
Additionally, for NaCl/ARM only:
|
|
||||||
|
|
||||||
% ln -nfs /opt/nacl_sdk/pepper_39/tools/nacl_helper_bootstrap_arm $GOPATH/bin/nacl_helper_bootstrap_arm
|
|
||||||
|
|
||||||
Support scripts
|
|
||||||
---------------
|
|
||||||
|
|
||||||
Symlink the two scripts in this directory into your $PATH, just as you did with
|
|
||||||
NaCl sdk above.
|
|
||||||
|
|
||||||
% ln -nfs $GOROOT/misc/nacl/go_nacl_amd64p32_exec $GOPATH/bin/go_nacl_amd64p32_exec
|
|
||||||
% ln -nfs $GOROOT/misc/nacl/go_nacl_386_exec $GOPATH/bin/go_nacl_386_exec
|
|
||||||
% ln -nfs $GOROOT/misc/nacl/go_nacl_arm_exec $GOPATH/bin/go_nacl_arm_exec
|
|
||||||
|
|
||||||
Building and testing
|
|
||||||
--------------------
|
|
||||||
|
|
||||||
Building for NaCl is similar to cross compiling for other platforms. However,
|
|
||||||
as it is not possible to ever build in a `native` NaCl environment, the cmd/go
|
|
||||||
tool has been enhanced to allow the full build, all.bash, to be executed,
|
|
||||||
rather than just the compile stage, make.bash.
|
|
||||||
|
|
||||||
The cmd/go tool knows that if GOOS is set to `nacl` it should not try to
|
|
||||||
execute any binaries itself. Instead it passes their execution to a support
|
|
||||||
script which sets up a Native Client environment and invokes the NaCl sandbox.
|
|
||||||
|
|
||||||
The script's name has a special format, go_$GOOS_$GOARCH_exec, so cmd/go can
|
|
||||||
find it.
|
|
||||||
|
|
||||||
In short, if the support scripts are in place, the cmd/go tool can be used as
|
|
||||||
per normal.
|
|
||||||
|
|
||||||
# Build and test Go for NaCl
|
|
||||||
|
|
||||||
NaCl does not permit direct file system access. Instead, package syscall
|
|
||||||
provides a simulated file system served by in-memory data. The script
|
|
||||||
nacltest.bash is the NaCl equivalent of all.bash. It builds NaCl with an
|
|
||||||
in-memory file system containing files needed for tests, and then it runs the
|
|
||||||
tests.
|
|
||||||
|
|
||||||
% cd go/src
|
|
||||||
% env GOARCH=amd64p32 ./nacltest.bash
|
|
||||||
|
|
||||||
Debugging
|
|
||||||
---------
|
|
||||||
|
|
||||||
Assuming that you have built nacl/amd64p32 binary ./mybin and can run as:
|
|
||||||
|
|
||||||
% sel_ldr_x86_64 -l /dev/null -S -e ./mybin
|
|
||||||
|
|
||||||
Create the nacl manifest file mybin.manifest with the following contents:
|
|
||||||
|
|
||||||
{ "program": { "x86-64": { "url": "mybin" } } }
|
|
||||||
|
|
||||||
url is the path to the binary relative to the manifest file.
|
|
||||||
Then, run the program as:
|
|
||||||
|
|
||||||
% sel_ldr_x86_64 -g -l /dev/null -S -e ./mybin
|
|
||||||
|
|
||||||
The -g flag instructs the loader to stop at startup. Then, in another console:
|
|
||||||
|
|
||||||
% /opt/nacl_sdk/pepper_39/toolchain/linux_x86_glibc/bin/x86_64-nacl-gdb
|
|
||||||
% nacl-manifest mybin.manifest
|
|
||||||
% target remote :4014
|
|
||||||
|
|
||||||
If you see that the program is stopped in _rt0_amd64p32_nacl, then symbols are
|
|
||||||
loaded successfully and you can type 'c' to start the program.
|
|
||||||
Next time you can automate it as:
|
|
||||||
|
|
||||||
% /opt/nacl_sdk/pepper_39/toolchain/linux_x86_glibc/bin/x86_64-nacl-gdb \
|
|
||||||
-ex 'nacl-manifest mybin.manifest' -ex 'target remote :4014'
